Role Summary

Our mission at HubSpot is to help millions of organizations grow better. On the Operations Web Team, you’ll play a critical role in ensuring the systems behind HubSpot’s digital experiences are reliable, scalable, and built to grow with our customers. This is a highly visible team responsible for delivering innovative web platforms and applications that power HubSpot’s global brand and are experienced by millions every day.

As a Senior DevOps Engineer, you’ll design and operate the infrastructure that supports high-traffic, data-intensive marketing platforms and systems. You'll also work across our Cloudflare edge platform, including opportunities to lead experiments and initiatives in areas like web personalization as they develop. You’ll partner closely with developers and stakeholders to improve delivery velocity while upholding strong standards for security, performance, and operational excellence. Together, we’re on a mission to build the best web experience in the world, and the reliability of our platforms is foundational to that goal.

What You’ll Do

• Design, build, and maintain scalable, secure, and reliable cloud infrastructure for high-traffic, business-critical applications, improving it through automation and observability.
• Operate and improve our Cloudflare edge platform (CDN, caching, WAF, DNS), and contribute to edge experiments and initiatives - such as traffic routing, staged rollouts, and personalization - as those efforts grow.
• Lead incident response, root cause analysis, and post-incident reviews, ensuring learnings are translated into systemic improvements.
• Build and maintain CI/CD pipelines, and establish and evolve infrastructure-as-code standards for consistency, scalability, and long-term maintainability.
• Use AI-assisted tooling in day-to-day DevOps work and help the team adopt what proves valuable for reliability, delivery velocity, and cost efficiency.
• Own medium-to-large infrastructure initiatives from design through production, including documentation, runbooks and long-term support.
• Contribute to sprint planning, backlog refinement, and roadmap planning, helping prioritize infrastructure investments that improve reliability, scalability, and developer velocity.
• Evaluate technical trade-offs and clearly communicate risks, impact, and recommendations to cross-functional stakeholders across Web Development, QA, and Product.
• Support the growth of less-experienced engineers through informal mentoring, code review, and sharing best practices in DevOps and cloud architecture.
